Book Description
The objective of this study was to examine traffic control for night work zones from the perspective of both agencies and motorists. This was accomplished by investigating practices of state departments of transportation, identifying the problems associated with traffic control for night work zones, and identifying potential strategies to resolve them. Reduced visibility, driver impairment or inattention, inadequate lighting, and difficulty in maintaining traffic control devices are common problems identified with night work zones based on surveys of state departments of transportation and residencies within the Virginia Department of Transportation. Having police present, making workers more visible, using drums in the taper, maintaining traffic control devices, and providing adequate lighting were common solutions. Based on the review of work zones, traffic control for night work zones is generally adequate. Common problem areas were properly establishing work zones based in accordance with the Virginia Work Area Protection Manual, maintaining the traffic control devices, and properly aiming and aligning lighting to avoid glare. Although there is a perception that night work zones are less safe than daytime work zones, evidence to substantiate this perception, such as higher accident rates, was not available because of a lack of accurate traffic exposure data. Based on a limited amount of data, there was no evidence of the perceived higher speeds at night.

Book Description
The increased demand on the current highway system has caused transportation agencies to increase scheduling for nighttime work in order to alleviate daytime work zone congestion, especially during peak traffic hours. Although traffic congestion is reduced, safety in nighttime workzones remains a concern among both transportation agencies and contractors. According to the Federal Highway Administration (FHWA), approximately one-half of the fatalities that occurred in workzones nationwide occurred at night. These work zone statistics have received increased attention among agencies to evaluate planning and safety issues concerning the workers and the general public on nighttime workzones. Four separate, but interrelated research studies were conducted between September 2005 - May 2007 to address safety issues in nighttime construction and maintenance projects on highways in Indiana. The first study investigated owner and contractor safety management planning for nighttime construction and maintenance operations, while the second study investigated traffic control planning and implementation procedures for nighttime construction and maintenance operations. The third study investigated the effectiveness of speed control measures on nighttime construction and maintenance projects and the fourth study evaluated the effectiveness of high-visibility personal protective equipment practices.

Book Description
"TRB's National Cooperative Highway Research Program (NCHRP) Report 726: A Guidebook for Nighttime Construction: Impacts on Safety, Quality, and Productivity provides suggested guidance on the conduct of nighttime highway construction and maintenance operations. These guidelines are based on best practices and strategies for nighttime operations that relate to the personnel and traveling public safety and the quality of the as-built facility. The guide also addresses work-zone risk analysis planning and implementation, construction nuisances to both neighbors and workers, and work-zone illumination methods."--Publisher's description.

Book Description
Information from driver studies performed during the first year of the project identified several features and conditions that created confusion and anxiety in traversing the work zone. Many of these conditions represented deficiencies in the work zone traffic control from the standpoint of positive guidance principles. This report describes the efforts to tailor the application of positive guidance procedures to work zone traffic control installations reviews. Four key steps, hazard visibility assessment, expectancy violation determination, information load analysis, and information needs specification, are described in the context of traffic control at potentially complex work zones. A methodology is presented for applying these steps in a field review process to be performed as part of the work zone traffic control installation process.

Book Description
Volume I illustrates many of the typical worksites describing the most common conditions encountered. The information provided can be used to supplement local, state, and national standards. The topics include, among others: Public information, regulatory control, special traffic provisions, protection of pedestrians, flagging, temporary traffic signals, and nighttime procedures. Volume II is intended primarily for use by job site supervisors. It addresses the most common situations, problems and solutions that supervisors might be faced with. The topics include, among others: Emergency work moving operations, temporary traffic control devices, placing devices, temporary removal of signs, and pedestrian needs.

Book Description
TRB¿s National Cooperative Highway Research Program (NCHRP) Report 627: Traffic Safety Evaluation of Nighttime and Daytime Work Zones explores the crash rates for nighttime and daytime work zones and examines management practices that promote safety and mobility in work zones. The report also highlights work-zone crash reporting suggestions designed to help improve the data collected on work zone crashes.
